FLIEGIEL, MERRIOK, NEW YORK HATCH oous'rauo'rrorr roa urrna DECKS Application fired January 5, 1932. Serial No. 584,876.

This invention relates generally to ships hatchesfand refers moreparticularly to an upper deck hatch construction which is 1n the nature of an improvement upon my prior 5 United States Letters Patent No. 1,835,856,

granted December 8, 1981;

In addition to attaining the general ob jects and advantages set forthin the previous patent above referred to, the present 1:) invention aims to simplify the means for supporting the hatch cover sections from the deck for shift-ing movement to and from covering and uncovering relations with respect to the hatchway and for raisingand lowering the cover sections.

The invention further resides in the provision of an improved packing and sealing means for rendering the hatch watertight without resorting to the use of tarpaulins.

' WVith these and other objects in mind, reference is made to the following specification and accompanying drawings, in which there is disclosed by way of example a single and preferred embodiment of the invention, while 11. the appended claims define the actual scope thereof. I

In the drawings:

' Referring to the drawings by characters of reference, A designates the top or shelter deck of a vessel formed with an opening or hatchway B having an upstandingor raised coaming C, preferably of steel. Theupper marginal edge of the coaming in the present instance provided with upwardly divergent inner and outer flanges l0 and 11 which define a substantially V-shapeol continuous channel lZ'for the reception of a packing or gasket 13, which is preferably of rubber. The inner confronting faces of the flanges V 10 and 11 adjacent the upper edges are formed with moulding strips 14 which are preferably half round and which are spaced from each other so as to receive therebetween and therebelow the packing or gasket 13.

' The hatch construction includes one-or more covers, depending upon its size, but in the present instance, the hatch includes two cover sections designated generally by the reference characters D and E, which sections are of identical construction and which include a top panel 15 of greater width and section, whichis designed to cooperate with the packed upper marginal edge ofthecoaming C, as clearly illustrated in Figures 3 and 7 of the drawings. This affords an effective means for sealing the hatch when closed by the cover torender the same watertight without resorting to the use of tar- Th-e protruding or overhanging are formed with an inner longitudinally eX- tending angle strip 18 and wlth an outer inverted lon itudinall extendin channel stri 19 which incidentally serve to strengthen the cover structure but which primarily constitute bearing means for depending supporting legs 20. The legs 20 in horizontal cross section are preferably channel shaped, with the "webs cut away adjacent the upperand son.

upper and lower portions 21 and 22 of the flanges, bifurcated parts. The upper furcations 21 receive therethrough a fulcrum bolt or pin 23 which extends through the depend ing flanges 24 of the channel 19 and through the depending flange 25 of the angle strip 18. Each leg 20 is provided with a lateral strut or brace 26 which is secured to the inner side thereof intermediate its height, and p which brace extends upwardly and inwardly with the upper extremity receiving therethrough the fulcrum bolt or pin 23. The spacing.

sleeve 27 surrounds the fulcrum bolt or pin 23 and is interposed between the upper terminal of the brace or strut 26 and the inner side flange 24 of the channel 19. This affords a wide fulcrum bearing for the upper end of the leg, making the supporting leg more stable and rigid laterally. The lower furcat-ions 22 receive therebetween a peripherally grooved wheel or roller 28 which is designed to embracingly engage a rail 29 on the deck B, it being understood that one rail is disposed on each side of the hatchway coaming C, as illustrated in Figure 3 of the drawings. Each leg 20 is of an appropriate length when disposed perpendicular to the deck, to position the hatchway above and clear of the coaming, whereby the covers may be rolled on the rails to and from their covering relation to the coaming. In order to limit the swinging of the legs and to afford a definite stop where the same will be perpendicular to the horizontal plane of the hatch covers and deck B, the upper furcartions 21 are provided with a flat 30 at right angles or perpendicular to the vertical free edge of the flanges of the legs. The flat 30 merges into a curved or arcuate portion 31 which is struck on a radius from the axial center of the fulcrum pin 23. This arrangement therefore permits the legs to be swung to an angular position with reference to the horizontal plane of the hatch covers and deck B, as illustrated in Figure 1 and in broken lines in Figure 5 of the drawings. It thus follows that when the hatch covers are located over the coaming, the legs when released will permit the covers to gravitate to a lowered seated position on the upper edge of the coaming.

As illustrated, each hatch cover D and E is provided with a plurality of legs 20 disposed on each side thereof and depending therefrom. The lower ends of the legs are connected by a link 35 to cause the legs on one side of each hatch cover to move in uni- Said links are preferably in the nature of rods, the opposite ends of which are threaded as at 36 to threadedly engage in yokes 37 which are fulcrumed on the roller shafts or trunnions 38.

The yoke 37 of the innermost leg is provided with inwardly directed extensions 39 spaced apart and traversed by a pin 40. This lower the hatch cover sections.

or sheave 43 may be supported in any desired manner, either from the deck, the rails or the provides means for engaging with the innermost leg, the book 41 at the terminal of a cable 42 which is designed to be trained over a sheave 43 and thence connected with suit able tackle for exerting an inward pull on each of the innermost legs to straighten the same for raising the hatch covers or for permitting the angular movement of the legs to The pulley sides of the coaming and, obviously, there will be a cable 42 for each side of each hatch cover section. v

In order to hold the legs in their vertical or perpendicular position to support the hatch cover sections elevated after they have been initially raised by the cables 42 and tackle, retaining bars 45 are employed for each of the innermost legs 20 of each hatch cover section, and said retaining bars are preferably provided with upper and lower bifurcated terminals 46 and 47. The upper furcations 46 are disposed between the depending flanges 24 of the channels 19 and are fulcrumed thereto by means of pins 48 which may be permanently or removably installed. The lower furcations of each retaining bar are designed to be received between the flanges of the channel shaped legs 20 and are apertured to receive the removable retaining pins 49 which may be locked in position by a cotter pin 50 and which are preferably anchored by chains 51 to the legs to avoid their loss and misplacement. It is. of course, understood that the flanges ofthe leg are correspondingly apertured and, if desired, each leg may be provided with an upper set of apertures 52 with which the lower furc tions 47 of the retaining bars may register to receive the retaining pins 49 when the hatch covers are lowered, thus serving to ock the hatch covers in their lowered seated posi tion on the coaming.

Obviously, the hatch covers when not in use may be stowed in any desired manner but, as illustrated in Figure 4 of the drawings, pairs of longitudinally spaced upstanding holders 55 and 56 may be provided adjacent one end of the coaming, which holders may form a part of the track rails 29 as illustrated. or otherwise. One hatch cover section may be received between each pair of holders an d 56 and the other between the holder 56 and the end of the coaming C. The innermost holders 56 may be provided with a pivoted upper end 57 which is swung downwardly to the dotted line position illustrated in Figure 4 until after the first hatch cover se tion has been stowed. After the first hatch cover section is stowed, the legs will be swung downwardly to the position illustrated in Figure 4, after which the terminals 57 will be swung upwardly-and the second hatch cover section stowed and its legs swung upwardly to the position illustrated inFigure 4. In practice, however, it is obvious that the hatch cover sections may be otherwise stowed, the illustration in Figure 4 merely showing one of th possibilities.

From the foregoing, it will, thus be seen that a hatch for upper decks has been devised in which the cover or cover sections are sup- 7. ported from the deck when not in active use,

cpl

whereby the same may be rolled to and from a stowed position, together with a means for sealing the covers against the entrance of water without the use of tarpaulins.

While a preferred embodiment of the invention has been illustrated, it is to be understood that variations and modifications which fall within the scope of the claims may be resorted to when desired. I
